Hello,

We are using CC1120, we tried to create a small program which implements sniff as in the swrc253d.zip example:

[Sorry for not posting using the code but the e2e is so slow i can't seem to open this without a timeout :\ ]

I was able to get up to 4 packets & no more than that while losing more than 80% of packets sent.

The code:

intit_CC1120_etc();

// Calibrate radio according to errata
manualCalibration(); //as in the example

// Calibrate the RCOSC
calibrateRCOsc(); //as in the expmle

mrfiSpiCmdStrobe( SWOR ); // Set radio in RX Sniff Mode

while (1)
{
    while (revicedPacket == 0);
    if (revicedPacket == 1)
    {
      BSP_TOGGLE_LED1();
      revicedPacket = 0;
    }
    mrfiSpiCmdStrobe( SWOR ); // Set radio in RX Sniff Mode

}

I've made some more tests & I'm sure, I miss something.
The test: I send 1 Tx packet (with SMARTRF_SETTING_PREAMBLE_CFG1 = 0x30 => 24 Bytes preamble) and test the messageIndex to verify that what I send is received.
The problem: I miss ALLOT of packets sometimes it is only 1 packet that is missing but most of the times much more.

As well as inserted re calibration upon receive of packet:

intit_CC1120_etc();

// Calibrate radio according to errata
manualCalibration(); //as in the example

// Calibrate the RCOSC
calibrateRCOsc(); //as in the expmle

mrfiSpiCmdStrobe( SWOR ); // Set radio in RX Sniff Mode

while (1)
{
while (revicedPacket == 0);
if (revicedPacket == 1)
{
BSP_TOGGLE_LED1();
revicedPacket = 0;

// Calibrate radio according to errata
manualCalibration();
// Calibrate the RCOSC
calibrateRCOsc();
uint8_t messageIndex = mrfiIncomingPacket_ptr->frame[TAG_M_TIND_IND];
}
mrfiSpiCmdStrobe( SWOR ); // Set radio in RX Sniff Mode

}

I guess I'm missing something but I've followed the examples for sniff in swrc253d.zip , please advice how to proceed.

I've changed configuration to as close as default in smart rf for RX:

I selected the 50 kbps settings in SmartRF Studio and then chose the RX Sniff Mode tab. I changed the preamble to 7 bytes and the CS threshold to -78 dBm. I then exported the settings to run with the CC112x Sniff mode code example on the web. I kept the IOCFGx configuration to be compliant with the code example. I was able to receive all packets that I sent. My settings are shown below:

// Packet length mode = Variable

// Packet length = 255

// Carrier frequency = 915.000000

// Manchester enable = false

// PA ramping = true

// Whitening = false

// Bit rate = 100

// Symbol rate = 50

// Deviation = 24.963379

// Modulation format = 4-GFSK

// RX filter BW = 100.000000

// Performance mode = High Performance

// Device address = 0

// TX power = 15

// Packet bit length = 0

// Address config = No address check
